Arguments

lprec

an lpSolve linear program model object.

columns

a numeric vector containing values from the set {1, ..., n} (where n is the number of decision variables in lprec) specifying which columns to set the mode for.

modes

a character vector composed of the strings {"ceiling", "floor", "auto", "default"} giving the branch modes for the decision variables specified in columns. Please see the reference for a description of these terms.
